<p>A video encoding/decoding apparatus and method for color images are provided. A first motion prediction unit generates a first prediction residue image for an input image on the basis of a first motion prediction result of the input image. An image information detection unit sets a predetermined color component among color components of an R-G-B image to a reference color component and determines whether the input image is a Y-Cb-Cr image or an R-G-B image and whether a color component of the input image is the reference color component. A second motion prediction unit performs motion prediction for the first prediction residue image and generates a second prediction residue image, on the basis of the reference color component, if the input image is the R-G-B image and if the color component of the input image is not the reference color component, thereby performing optimal encoding/decoding according to the color information. <IMAGE></p> |
